Ednding in two hours. I hear rumors that this is THE Rarest SNES test Cartridge, with 100 produced being thrown around. Cant find any confirmation or disproving info on it either.
Ending at the same time are a NES NTF2 1.1, NES Joystick Test and a SNES NTF 2.5.
You can also check out the NES and SNES test cartridges they’ve sold recently.
